Four of these records – for distance and duration in two ballooning classes – still stand today. On completing the flight, Jones told the jubilant, Geneva-based mission control team: “The first thing I'll do is phone my wife, and then, like the good Englishman I am, I'll have a cup of tea.''

Piccard, 41 at the time, added that he felt an “invisible hand” had guided their “fantastic voyage”.

About the round-the-world flight

Piccard and Jones’ historic journey began when they took off from the Swiss ski village of Château d’Oex, and ended some three weeks later in Egypt – taking in Asia, the Pacific Ocean, Central America, and the Atlantic Ocean on the way.

Their balloon, the Breitling Orbiter 3, was a huge silver orb that stood 55m high when fully inflated. Known as a Rozière – or Rozier – balloon, it combined the features of a hot air balloon with those of a gas balloon, incorporating a helium cell within a hot air envelope.

With a Rozier balloon, the hot air prevents the lifting gas cooling down at night and causing the balloon to lose altitude. It’s a principle invented in 1785, albeit using hydrogen rather than helium, which is a much safer option.

The red gondola in which Piccard and Jones made their 1999 voyage was equipped with navigation tools and survival gear, as well as a single bunk and a pressure-operated toilet.
It is now on display at the National Air and Space Museum in Washington DC, USA.
